JOHN R. ROGERS, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGENTHALER LINO-TYPE COMPANY, A CORPORATION OF NEW YORK.

MATRIX FOR LINE-CASTING MACHINES.

To all whom it may concern:

Be it known that I, JOHN R. Roonns, of the borough of Brooklyn, countyof Kings, and State of New York, have invented a new and usefulImprovement in Matrices for Line-Casting Machines, of which thefollowing is a specification.

My invention has reference to matrices intended. more particularly foruse in line casting machines of the Mergenthaler type, represented inLetters Patent of the United States et36,532.

The circulating matrices in each font or set are of various thicknesses,according to the width of the characters contained in their edges. Theyare held in a magazine in the machine, selected in the required order,assembled temporarily in line, the line presented momentarily to a moldand thereafter delivered to the distributing mechanism, by which theindividual matrices are returned to their respective channels in themagazine. For reasons unnecessary to detail herein, it is desirable tofeed the thin matrices to the distributing mechanism at shorterintervals than the thick matrices.

The objectof the present invention is to produce thick matrices of suchform that the mechanism for delivering them to the distributor willdeliver them slowly, or at relatively long intervals, although the samemechanism will deliver the thin matrices, of ordinary form, at shorterintervals. \Vith this end in view I construct my improved matrix with anadditional shoulder or hearing surface adapted to be acted upon by thedevice which lifts the matrices one at a time from the composed line tothe distributer.

In the drawings: Figure 1 represents, in perspective, a matrix of myimproved form. Figs. 2 and 8 are edge views illustrating the manner inwhich this matrix cooperates with the lifting or feeding device.

Referring to the drawings, A represents the matrix consisting of a fiatplate having one or more characters or matrices, a, in one edge andhaving also at opposite ends the ears (4 and a projecting edgewisebeyond the body of the matrix. At the upper end the matrix is formedwith a Vshaped notch, a, provided with teeth to cooperate with theSpecification of Letters Patent.

distributer bar of the machine, the matrix at this point being reducedin thickness, so that the teeth are contained in the thin or reducedportion at one side of the body.

So far as described the matrix may be in all respects like thoseemployed in the Mergenthaler machine.

The novel feature constituting the subject of my invention consists inthe shoulder Z) lying horizontally across the matrix near the lower endand on the opposite side from that which carries the distributing teeth,that is to say on the side at which the ears a and a are located, inposition to be acted upon by a lifting finger, C, or any equivalentdevice for lifting matrices one at a time to the distributer. Thisshoulder may be modified in form. For example, instead of being extendedentirely across the matrix from one edge to the other it may becentrally located. In short it may be of any suitable form, providedthat the lifting device which is adapted to act against the lower end ofthe matrix body may first act against the lifting shoulder. The locationof the distributing teeth on one side of the matrix and the shoulder Z)on the opposite side is necessary in order that they may cooperate withthe various mechanisms of the line casting machine.

Having described my invention, what I claim and desire to secure byLetters Patent. is:

1. A matrix of the class described, having the laterally projecting carsa and a and having also, on the same side with the ears, a shoulder, b.

2. A matrix of the class described, having the toothed notch a at theupper end at one side, and a shoulder, I), at the lower end at theopposite side.

A matrix of the class described, having at the lower end the projectingears, a and a horizontal shoulder, 6, located above the lower sides ofthe ears.

In testimony whereof I hereunto set my hand this twenty-ninth day ofApril, 1909, in the presence of two attesting witnesses.

JOHN R. ROGERS.
